#SpaceX postponed the Polaris Dawn launch from #KSC due to rough seas downrange in the potential recovery area should Dragon have to abort. That allowed the Starlink launch to proceed at #CCSFS. The #Falcon9 burst into flames upon landing on the drone ship, toppled over and exploded.
SpaceX postponed another F9 launch at Vandenberg to study what happened.
Go to the 14:15 mark on the SpaceX website video if you want to see the failure.
